LM Pinout, Features, Equivalents & Datasheet

Submitted by webmaster on 23 November Available in TO package only. When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a reference voltage.

For the years, see 8th millennium. You can also check on 78 series for positive voltage regulators. In other projects Wikimedia Commons. The LM78S40 from Fairchild is not part of the 78xx family and daasheet not use the same design.

PDF LM7912 Datasheet ( Hoja de datos )

TL — Programmable Reference Voltage. LM Applications Constant V output regulator to use as power or reference voltage for analog and digital circuits. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2. Articles needing additional references from January All articles needing additional references.


Hence, I have interchanged the polarity of the battery. Please help improve this article by adding citations to reliable sources. The SR from Datel is a full switching power supply module designed as a drop-in replacement for 78xx chipsand not a linear regulator like the 78xx ICs.

lm datasheet & applicatoin notes – Datasheet Archive

The circuit diagram for those can be found at the datasheet given at the end of this page. Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. Retrieved from ” https: Mastering the Raspberry Pi.

These devices support an input voltage anywhere from around 2.

There are many other ways in which the IC can be used based on your application. From Wikipedia, the free encyclopedia. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices.

Cool Projects for Datashset Source Hardware. This article needs additional citations for verification. In both cases will be an ideal choice when you need a negative 12V.

Unsourced material may be challenged and removed. A very basic Voltage regulator circuit is shown below. By using this site, you agree to the Terms of Use and Privacy Policy.


LM7912 Datasheet

The value of the capacitors need not be the exact values, you can use the closest value datasheeet have got. Industrial Electronics and Control. January Learn how and when to remove this datqsheet message. Meaning it will provide a constant output voltage of V when the input voltage is between Encyclopedia of Electronic Components Volume 1: Complete Technical Details can be found at the datasheet given at the end of this page.

I have used a Battery to power the IC, but you can use any power source but notice that the supply voltage should be negative. The 78xx line are positive voltage regulators: There is a related line of 79xx devices which are complementary negative ml7912 regulators.

LM belongs to the family of Voltage regulators. Some devices provide slightly different voltages than usual, such as the LM78L62 6. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost.

This page was last edited on 5 Decemberat The Input lm9712 output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively.
